6. VLAN Setting
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would
allow you to isolate network traffic, so only the members of the same VLAN will receive traffic
from the ones of the same VLAN. Basically, creating a VLAN from a switch is logically equivalent of
reconnecting a group of network devices to another Layer 2 switch. However, all the network
devices are still plugged into the same switch physically.
6.1 VLAN Mode
You may select the VLAN Mode of the switch. Port-based VLAN is for separating traffic only on this
single switch. There is no handover of network traffic within VLAN groups to other switches. For
the handover to other switches use Tag Based VLAN. In VLAN Mode you can switch from Tag to
Port Based VLAN. Port Based VLAN is the default mode.
After having switched to Tag Based VLAN Mode, the screen changes. On this screen you can now
define and configure your Up- and Downlink ports. These are important since here the handover
between the switches of your network takes place.

VLAN Mode: Displays VLAN mode: port based/Tag based VLAN. Here you can also switch back
to Port Based VLAN Mode

Add tag means the outgoing packet of the selected port will be inserted a 802.1Q tag. Use this
setting for your Up- and Downlink Ports in your VLAN Tagged Network.

Don’t care means the outgoing packet of the selected port keep the original packet received at
